I took up Go about six months ago, after many false starts over the years. The secret for me was to stop playing computers and start playing humans online (I like online-go.com). Computers at lower difficulty settings make a combination of very strong moves and very weird moves, which are difficult for beginners to interpret. And the game is just a lot more fun when playing against people of similar skill level or a bit stronger, so you win about 50% of games and can understand your opponents' moves more easily.
